A micro-enterprise (or microenterprise) is generally defined as a small business employing nine people or fewer, and having a balance sheet or turnover less than a certain amount (e.g. 2,000,000 euros or PhP 3,000,000). The terms microenterprise and microbusiness have the same meaning, though traditionally when referring to a small business financed by microcredit the term microenterprise is often used. Similarly, when referring to a small, usually legal business that is not financed by microcredit, the term microbusiness is often used. Internationally, most microenterprises are family businesses employing one or two persons. Most microenterprise owners are primarily interested in earning a living to support themselves and their families. They only grow the business when something in their lives changes and they need to generate a larger income. According to information found on the Census.gov website, microenterprises make up 95% of the 28 million US companies tracked by the census.
